When we were outputting class members for `setClassMetadata` calls,
we were using the string representation of the member name. This can
lead to us generating invalid code when the name contains dashes and
is quoted (e.g. `@Output() 'has-dashes' = new EventEmitter()`), because
the quotes will be stripped for the string representation.
These changes fix the issue by using the original name AST node that was
used for the declaration and which knows whether it's supposed to be
quoted or not.

For attribute bindings that target a directive's input, the template
type checker is able to verify that the type of the input expression is
compatible with the directive's declaration for said input. This
checking adheres to the `strictNullChecks` flag as configured in the
TypeScript compilation, such that errors are reported for expressions
that include `undefined` or `null` in their type if the input's
declaration does not include those types.
There was a bug with this level of type-checking for directives that
also declare coercion members, where binding an expression that includes
the `undefined` type to a directive's input that does not include the
`undefined` type would not be reported as error.
This commit fixes the bug by changing the type-constructor in type-check
code to use an intersection type of regular inputs and coerced inputs,
instead of a union type. The union type would inadvertently allow
`undefined` types to be assigned into the regular inputs, as that would
still satisfy the characteristics of a union type.
As a result of this change, you may start to see build failures if
`strictTemplates` is enabled and `strictInputTypes` is not disabled.
These errors are legitimate and some action is required to achieve a
successful build:
1. Update the templates for which an error is reported and introduce the
non-null assertion operator at the end of the expression. This
removes the `undefined` type from the expression's type, making it
appear as a valid assignment.
2. Disable `strictNullInputTypes` in the compiler options. This will
implicitly add the non-null assertion operators similar to option 1,
but all templates in the compilation are affected.
3. Update the directive's input declaration to include the `undefined`
type, if the directive is not implemented in an external library.

Previously, the [processCliCommands][1] dgeni processor, which is used
to generate the docs pages for the CLI commands, expected the CLI
commands overview page (with a URL of `cli`) to exist as a child of a
top-level navigation section (`CLI Commands`). If one tried to move the
`CLI Commands` section inside another section, `processCliCommnads`
would fail to find it and thus fail to generate the CLI commands docs.
This problem came up in #38353.
This commit updates the `processCliCommands` processor to be able to
find it regardless of the position of the `CLI Commands` section inside
the navigation doc.

Roll forward of #38147.
This allows Closure compiler to tree shake unused constructor calls to `NgModuleFactory`, which is otherwise considered
side-effectful. The Angular compiler generates factory objects which are exported but typically not used, as they are
only needed for compatibility with View Engine. This results in top-level constructor calls, such as:
```typescript
export const FooNgFactory = new NgModuleFactory(Foo);
```
`NgModuleFactory` has a side-effecting constructor, so this statement cannot be tree shaken, even if `FooNgFactory` is
never imported. The `NgModuleFactory` continues to reference its associated `NgModule` and prevents the module and all
its unused dependencies from being tree shaken, making Closure builds significantly larger than necessary.
The fix here is to wrap `NgModuleFactory` constructor with `noSideEffects(() => /* ... */)`, which tricks the Closure
compiler into assuming that the invoked function has no side effects. This allows it to tree-shake unused
`NgModuleFactory()` constructors when they aren't imported. Since the factory can be removed, the module can also be
removed (if nothing else references it), thus tree shaking unused dependencies as expected.
The one notable edge case is for lazy loaded modules. Internally, lazy loading is done as a side effect when the lazy
script is evaluated. For Angular, this side effect is registering the `NgModule`. In Ivy this is done by the
`NgModuleFactory` constructor, so lazy loaded modules **cannot** have their top-level `NgModuleFactory` constructor
call tree shaken. We handle this case by looking for the `id` field on `@NgModule` annotations. All lazy loaded modules
include an `id`. When this `id` is found, the `NgModuleFactory` is generated **without** with `noSideEffects()` call,
so Closure will not tree shake it and the module will lazy-load correctly.

Previously, each Angular repository had its own strategy/configuration
for merging pull requests and cherry-picking. We worked out a new
strategy for labeling/branching/versioning that should be the canonical
strategy for all actively maintained projects in the Angular organization.
This PR provides a `ng-dev` merge configuration that implements the
labeling/branching/merging as per the approved proposal.
See the following document for the proposal this commit is based on
for the merge script labeling/branching: https://docs.google.com/document/d/197kVillDwx-RZtSVOBtPb4BBIAw0E9RT3q3v6DZkykU
The merge tool label configuration can be conveniently accesed
within each `.ng-dev` configuration, and can also be extended
if there are special labels on individual projects. This is one
of the reasons why the labels are not directly built into the
merge script. The script should remain unopinionated and flexible.
The configuration is conceptually powerful enough to achieve the
procedures as outlined in the versioning/branching/labeling proposal.
PR Close#38223
The merge tool provides a way for configurations to determine the branches
for a label lazily. This is supported because it allows labels to respect
the currently selected base branch through the Github UI. e.g. if `target: label`
is applied on a PR and the PR is based on the patch branch, then the change
could only go into the selected target branch, while if it would be based on
`master`, the change would be cherry-picked to `master` too. This allows for
convenient back-porting of changes if they did not apply cleanly to the primary
development branch (`master`).
We want to expand this function so that it is possible to report failures if an
invalid target label is appplied (e.g. `target: major` not allowed in
some situations), or if the Github base branch is not valid for the given target
label (e.g. if `target: lts` is used, but it's not based on a LTS branch).
PR Close#38223
The merge script currently accepts a configuration function that will
be invoked _only_ when the `ng-dev merge` command is executed. This
has been done that way because the merge tooling usually relies on
external requests to Git or NPM for constructing the branch configurations.
We do not want to perform these slow external queries on any `ng-dev` command
though, so this became a lazily invoked function.
This commit adds support for these configuration functions to run
asynchronously (by returning a Promise that will be awaited), so that
requests could also be made to the Github API. This is benefical as it
could avoid dependence on the local Git state and the HTTP requests
are more powerful/faster.
Additionally, in order to be able to perform Github API requests
with an authenticated instance, the merge tool will pass through
a `GithubClient` instance that uses the specified `--github-token`
(or from the environment). This ensures that all API requests use
the same `GithubClient` instance and can be authenticated (mitigating
potential rate limits).

@angular/core/testing provide `async` test utility, but the name `async` is
confusing with the javascript keyword `async`. And in some test case, if you
want to use both the `async` from `@angular/core/testing` and `async/await`,
you may have to write the code like this.
```typescript
it('test async operations', async(async() => {
const result = await asyncMethod();
expect(result).toEqual('expected');
}));
```
So in this PR, the `async` is renamed to `waitForAsync` and also deprecate `async`.

Within an angular template, when a character entity is unable to be parsed, previously a generic
unexpected character error was thrown. This does not properly express the issue that was discovered
as the issue is actually caused by the discovered character making the whole of the entity unparsable.
The compiler will now instead inform via the error message what string was attempted to be parsed
and what it was attempted to be parsed as.
Example, for this template:
```
<p>
ģp
</p>
```
Before this change:
`Unexpected character "p"`
After this change:
`Unable to parse entity "ģp" - hexadecimal character reference entities must end with ";"`
